This iiiyention relates to the ribbon ineehaiiisiii of front strike writing iiairhii'ies of the l lli(l in whieh either one or another eolor of ribbon can he used at will. ii The principal object oi the present lliYtlia tion is to provide a simple i'lei'ire reiiilily applieable. to existing maeliines of this kind, tor rendering the ribbon inaetiye at the, type strokes, so that the types may strike ott' the ribbon as when w 'itiin; steneils ii The improvement shown in iroiineetion with a hiehronie ribbon mechanism, in Willt'll 1 two fields of color are uniteil in a single ribhon, and in which two keys are PtOYitlUtl, l 1 one. for each color ol ribbon, so that upon ilepressiiig either key the t'()l'l't.-.])t)litlllli (-olor or field of ribbon is caused to (-over the printing point at the type strokes. ln aililitioii to said keys, I proviile a lever \\'lllt'li ii is normally in itllO position, but may ho ii swung to a position to ('llHCOlltlltl' or ilisablo 1 tho rihboirvibrating le\'iees,so as to enable the types to write oil from the ribbon]. The lever is shown in connection with a ('i'osso arm bearing the two eolor keys :iiiil having a projoetlon which is engageable by a ram notchtoriiietl upon the lever, for the purpose a speei tied] 1 It will be seen thatalthough a siiigleribhon is shown, the device. is also applicable to iiiaehiiies in whieh two ribbons are i-oii ti'olleil by similar keys or equivalent. tlOVlLiS. In the accompanying drawings, Figure 1' is a perspective rear .viewof the present tin-- proyeiiient applied to an l iiilerwooil trout strike writing iiiaehine; the ribboii-vibrating ineehaiiisiii being: shown as liitlltt'ilV at the type st i'okes the type liQltW in pl'ilitlli-" position above the ribbon. .l ig. 2 is a seetional l llai'ttoril, in the eounty of Hartford tilitl i a l i l l l inoehaiiisin iii saiil maehiiie. bar 5 \'ll)liltt(l by the type-l ars. is tlXttl t' the ribbon actuator aiiil the ('oiiiieeteil lover aiiil ribboii-\ibr:itoi'Z the parts shown in normal positions.
